I am working on an old project that is like a 2d platformer, I have drawn two animated sprites and and one can jump in parabolic fashion. I have also drawn three flowers and some brick wall. what I would like to know is what I should add to my game. here is a screen shot

1. Add multiplayer (or cooperative) modes using sockets. Make very simple chat to start and make the Tic-Tac-Toe Game using sockets. And you will have everything to make MMORPG and 2D platformers with multiplayer/cooperative.
2. Try to add physics in your game using Box2D.
3. Study how to make GUI. Make your first button to start your game. Make a text edit element to enter a player name, a port and a host address.
4. Practice a lot by making simple games and examples and have a fun.

@8Observer8well to keep things simple I am working on getting the sprites to face either left or right and to move and jump in that direction, do you have any advice?

Okay, I will try to make a simple example using Qt C++ OpenGL 3.3 for practice. Qt just have a few helper classes to simplify working with shaders, VBO's, textures, resources, events and so on. But I think you will be able to translate my code to GLFW, SDL2, FreeGLUT and so on.

I change a face direction by changing the sign of “x scale” in model matrix:

    
    if (m_isRightDir)
    {
        m_playerModelMatrix.scale(16.0f, 16.0f);
    }
    else
    {
        m_playerModelMatrix.scale(-16.0f, 16.0f);
    }

This is a current of my example. I want to add jumping and collision. I did not made it in pure C++ and OpenGL 3.3. I will not use Box2D for this example.

well I have got my sprite to move to right but not to the left, I am using a boolean as a directional toggle, here is my code

void renderScene(void)
{
	glClear(GL_COLOR_BUFFER_BIT);
	glPushMatrix();
	drawBkgnd();
	drawBkgndone();
	drawBkgndtwo();
	drawWallone();
	drawFlowerone();
	drawFlowertwo();
	drawFlowerthree();
	if (move_left == true)
	{
		drawSpriteone();
		move_right = false;
	}
	else if (move_right == true)
	{
	drawSprite();
	move_left = false;
	}
	drawEnemySprite();
	glPopMatrix();
	glutSwapBuffers();
}

Do not use legacy/deprecated version of OpenGL. Use OpenGL 3+. This tutorial is good to start: https://learnopengl.com/​​​ Read the tutorial and rewrite your code to modern OpenGL.
